The VisionRGB-E1S works on my B550 at least.

I am running Datapath VisionAV capture with the VCS software and I just can't get proper colors. Everything is too dark. For instance in this screenshot the white color is rgb(239, 239, 239) instead of (255, 255, 255) and the blue widow bar is (0, 0, 112) instead of (0, 0, 128). With the original …

With a K6 300 (bottlenecking), I've seen temps reduced by up to 4 C load and idle by downclocking from 143 to 100 MHz, with 0-5% loss in performance up to 800 x 600 (tested in Quake 3, Need for Speed 5, 3DMark 99). So not a big reduction in temps, but also no clear benefit in running the card full …

Anyone ever encountered this and knows a solution? I've seen the same with a VisionRGB-E1S. I don't think the VisionRGB-PRO2 had the problem, but I can't remember for sure. It should be possible to fine-tune the positioning via the video card's control panel (if supported - Matrox at least should) …

This might be a stupid question but I'm trying to understand the aspect ratio setting: Capturing an input resolution of 640x400, is forced aspect ratio 4:3 and output resolution to 200% the same as setting aspect ratio to native and output resolution to 1067x800? It might be slightly slower with …

(Fortunately, like Datapath, Magewell has their own hardware API. Might have to take up programming just to code up a better interface that lets me make adjustments in increments of 1 and type in correct values directly.) The Magewell can probably be supported in VCS just by implementing the …

As this seems to be the main place for VCS issues, I thought I would share a discovery in case it relates to anyone else. I couldn't get VCS working at all on my system with the VisionRGB-X2 aka DGC133E. It's a PCI-X card and is installed in the only PCI-X board I have, an HP OEM version of the TR- …

Hi vvbee, I recently bought a TravelMate 4000M. How can i remove/replaace the hard drive? Do I need to remove all the screws at the bottom? Thanks! Can't remember, sorry. Maybe you did need to take off the whole case. I do know the laptop's plastic is brittle and the monitor hinge is especially …

The binary's again now hosted on GitHub, https://github.com/leikareipa/vcs/releases, since the server isn't coming back any time soon. Keep in mind it's an evaluation version. If you continue using it, you're required to leave ten bucks on a bench next time you go out. If that's illegal in your area …

Any chance you could share your built version? I tried building this now for a couple of hours but no luck. I have no experience with this tool chain. At least for me the information on github and comments here are not enough to get me going. For building OpenCV, see if the answer over at https:// …

Sounds good, and good that the docs were enough to get you going. It's just the nature of free open source that you need to do some legwork. I spent maybe 100 hours over just two weeks preparing the latest couple versions, so imagine having to do even more work. Any version of VCS from maybe two …

I've done it a bunch already, just on vacation from it now I guess. But it's open source with build instructions, there shouldn't be any secret sauce to it.

Version 2.4.0 is out, download it while it's up for the next few days. Same deal as last year - money's tight and I want to save on hosting, so the downloads will take a summer break. Not planning on putting them on GitHub now but maybe later - already done 40+ releases of this thing, that's enough …

Wouldn't it be easier to just split the VGA signal with a cable? If you are after a way to play games on LCD monitors than a dedicated scaler is going to work a lot better. Capture cards aren't designed for playing games. You can run into lots of different kinds of issues. You'll run into issues …

I tested with a VisionRGB-PRO using a PS2 keyboard via a switch box, recording a smartphone 960 FPS video of both the keyboard's caps lock light and an OS indicator displayed on a 60 Hz non-gaming monitor. Took about 30-40 ms from the caps lock light to a VisionRGB-captured image of Win 98's WordPad …
